The hidden features of elliptical galaxies

Elliptical galaxies are one of the three main types of galaxies, when galaxies are classified based upon their optical appearance (others: spiral and irregular). According to optical images, elliptical galaxies are also the most boring, with smoothly distributed stellar light without notable stellar concentrations or dust obscuration. However, new data from integral-field spectroscopy and imaging in non-optical wavelengths show that many elliptical galaxies are much more complicated than they appear. I will summarize what we have recently learned about the dynamics of elliptical galaxies from integral field-spectroscopy and what we have learned about their gas content and from radio and mm-interferometry.
